Question

The length and breadth of a rectangle are in the ratio of 3 :1 .If the perimeter of the rectangle is 72 m, then the length of the rectangle is?

Answer 1

Let the ratio be x Length=3x Breadth=x Formula of perimeter of a rectangle=2(L+B) 2(3x+x) 2*4x 8x ATQ, 8x=72 x=9m Length =3x 3*9m 27m Breadth =x 9m
